Scott Adams does use real-life situations when creating his cartoons but if you read some of the previous ones from this set, he's not directing this at the audio industry. I guess it was just a funny coincidence.

Thanks for the idea.I recently bought a recycled teak table which was a little too tall so I cut the legs down by about 40mm. Don't know why I I kept the pieces but, mysteriously, one has gone missing. I'm gonna check the dimensions and if they're close, they'll be under my amp on the weekend.
